The aim of this translational, randomized, controlled, blinded preclinical trial was to determine the effect of compound 21 (C21) in embolic stroke. Rats were subjected to embolic-middle cerebral artery occlusion (eMCAO). They received C21 (0.01, 0.03 and 0.06 mg/kg/d) or saline (orally) for five days, with the first-dose given IV at 3 h post-eMCAO. For the time-window study, the optimal-dose of C21 was initiated at 3, 6 or 24 h post-eMCAO and continued for five days. For the combinatorial study, animals received IV-tissue plasminogen activator (tPA) at either 2 or 4 h, with IV-C21 (0...

BACKGROUND: Phosphodiesterase 10A is a member of the phosphodiesterase family whose brain expression is restricted to the striatum. Phosphodiesterase 10A regulates cyclic adenosine monophosphate and cyclic guanosine monophosphate, which mediate responses to dopamine receptor activation, and the levels of these cyclic nucleotides are decreased in experimental models of l-dopa-induced dyskinesia. The elevation of cyclic adenosine monophosphate/cyclic guanosine monophosphate levels by phosphodiesterase 10A inhibition may thus be targeted to reduce l-dopa-induced dyskinesia...

BACKGROUND: Although spinal and bulbar muscular atrophy (SBMA) has been classified as a motor neuron disease, several reports have indicated the primary involvement of skeletal muscle in the pathogenesis of this devastating disease. Recent studies reported decreased intramuscular creatine levels in skeletal muscles in both patients with SBMA and transgenic mouse models of SBMA, which appears to contribute to muscle weakness. OBJECTIVE: The present study aimed to examine the efficacy and safety of oral creatine supplementation to improve motor function in patients with SBMA...

Recurrent deletions of a ~600-kb region of 16p11.2 have been associated with a highly penetrant form of childhood apraxia of speech (CAS). Yet prior findings have been based on a small, potentially biased sample using retrospectively collected data. We examine the prevalence of CAS in a larger cohort of individuals with 16p11.2 deletion using a prospectively designed assessment battery. The broader speech and language phenotype associated with carrying this deletion was also examined. 55 participants with 16p11...

BACKGROUND: Despite appropriate therapeutic interventions, progressive optic pathway glioma (OPG) in children may result in loss of vision and other neurologic morbidities. Molecularly targeted therapy against the MAP kinase pathway holds promise in improving outcomes while resulting in lower treatment-related toxicities. We report two children with refractory OPG who had a substantial and early reversal of their neurologic deficits and an impressive imaging response of their tumor to BRAFV600E inhibition therapy...

Opicapone (OPC) is a novel, potent, reversible, and purely peripheral third-generation COMT inhibitor, which provides an enhancement in levodopa (L-Dopa) availability. It represents adjunctive therapy for L-Dopa treated patients with PD and motor fluctuations. Areas covered: The purpose of this study was to evaluate pharmacokinetic of OPC for the treatment of PD. Expert commentary: Oral OPC exhibits linear, dose-dependent absorption. However, following concomitant ingestion of a high-fat, high-calorie meal, the maximum plasma concentration will be decreased...

We describe an 86-year-old woman with a history of hypertension who presented sudden disturbances of consciousness and left hemiparesis. Brain magnetic resonance imaging (MRI) revealed diffused hyperintensive changes on T2-weighted images localized subcortically in the white matter of both cerebral hemispheres, corresponding to acute vasogenic edema, causing moderate mass effect. Posterior reversible encephalopathy syndrome was initially diagnosed. After implementation of anti-edema intravenous steroid treatment and hypotensive therapy the symptoms began to retire, till the total regression...

INTRODUCTION: Meta-analyses report that more than 50% of patients who had a stroke suffer from moderate to severe sleep apnoea (SA), with adherence rates to positive airway pressure (PAP) therapy of only 30%. The primary objective of this study is to determine whether PAP adherence in patients who had a stroke with obstructive sleep apnoea (OSA) can be improved by a PAP training strategy during inhospital rehabilitation combined with a telemedicine monitoring system after discharge. Further objectives are (1) to compare the validity of a non-attended level-III polygraphy with that of a level-II polysomnography (PSG) in the diagnosis of SA, (2) to compare the validity of an apnoea-hypopnoea index (AHI) yielded by the PAP device with that obtained during PSG, (3) to determine changes in nocturnal systolic blood pressure (BP) due to PAP therapy with the pulse transit time (PTT) method and (4) to assess the impact of telemonitored PAP therapy on neurorehabilitation outcome parameters...

The only three oral treatments currently available for multiple sclerosis (MS) target the relapsing forms of the disease and concerns regarding efficacy, safety and tolerability limit their use. Identifying novel oral disease-modifying therapies for MS, targeting both its inflammatory and neurodegenerative components is still a major goal. AIM: The scope of this study was to provide evidence that the oral administration of C-Phycocyanin (C-PC), the main biliprotein of the Spirulina platensis cyanobacteria and its tetrapyrrolic prosthetic group, Phycocyanobilin (PCB), exert ameliorating actions on rodent models of experimental autoimmune encephalomyelitis (EAE)...

Advanced Parkinson's disease (APD) is characterized by increased functional disability, caused by motor complications, the presence of axial symptoms, and emergent disease- and drug-related non-motor symptoms. One of the advanced therapies available is intrajejunal infusion of levodopa/carbidopa intestinal gel (LCIG); however, patient selection for this treatment is sometimes difficult, particularly because of overlapping indications with other alternatives. In recent years, strong evidence has supported the use of LCIG in treating motor fluctuations associated with APD, and several clinical studies provide emerging evidence for additional benefits of LCIG treatment in certain patients...

Appearance of L-DOPA-induced dyskinesia (LID) represents a major limitation in the pharmacological therapy with the dopamine precursor L-DOPA. Indeed, the vast majority of parkinsonian patients develop dyskinesia within 9-10 years of L-DOPA oral administration. This makes the discovery of new therapeutic strategies an important need. In the last decades, several animal models of Parkinson's disease (PD) have been developed, to both study mechanisms underlying PD pathology and treatment-induced side effects (i...

Tegoprazan [( S )-4-((5,7-difluorochroman-4-yl)oxy)- N , N ,2-trimethyl-1 H -benzo[d]imidazole-6-carboxamide], a potassium-competitive acid blocker (P-CAB), is a novel potent and highly selective inhibitor of gastric H+ /K+ -ATPase. Tegoprazan inhibited porcine, canine, and human H+ /K+ -ATPases in vitro with IC50 values ranging from 0.29 to 0.52 μ M, while that for canine kidney Na+ /K+ -ATPase was more than 100 μ M. A kinetic analysis revealed that tegoprazan inhibited H+ /K+ -ATPase in a potassium-competitive manner and the binding was reversible...

Levodopa is the most effective antiparkinsonian agent, but chronic treatment is associated with the development of motor complications in the majority of patients with PD. Recent scientific and clinical advances are improving this situation. Long-term, double-blind studies demonstrate that dose is an important risk factor for the development of both motor fluctuations and dyskinesia, and suggest that it is best to use low doses of l-dopa when possible. Inhaled l-dopa and sublingual apomorphine are now being developed as rescue therapies that permit rapid and predictable reversal of off periods...

The transcription factor Nrf2 is known to induce gene expression of antioxidant enzymes and proteasome subunits. Because both oxidative stress and protein aggregation have damaging effects on neurons, activation of the Nrf2 signaling should be beneficial against neurodegeneration. In this study, we report a novel synthetic morpholine-containing chalcone KMS99220 that confers neuroprotection. It showed high binding affinity to the Nrf2 inhibitory protein Keap-1 and increased nuclear translocation of Nrf2 and gene expression of the antioxidant enzymes heme oxygenase-1, NAD(P)H:quinone oxidoreductase-1, and the catalytic and modifier subunits of glutamate-cysteine ligase in dopaminergic CATH...
